[XEN PATCH v2 0/3] address some violations of MISRA C Rule 8.4

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

MISRA C:2012 Rule 8.4 states:
"A compatible declaration shall be visible when an object or function with
external linkage is defined".

Changes from v1:
- Patch 1/7 has been committed;
- Patch 2/7 has been dropped, as the fix is already part of [1];
- Patch 3/7 drops the addition of asmlinkage on variables. Discussion on how to
  handle the existing uses can be part of a separate patch;
- Patch 4/7 is unchanged;
- Patch 5/7 has been committed;
- Patch 6/7 has been dropped
- Patch 7/7 has been revised to have a declaration for first_valid_mfn, rather
  than a deviation for the absence of a declaration
